Frequently Asked Questions - JN-i432TUR Japannext

How to connect the monitor to a computer?

Make sure the monitor and computer are turned off. Connect the power cable and an HDMI cable to the monitor, then connect this cable to the computer. Turn on the monitor first, then the computer. Select the appropriate HDMI source via the input button on the remote control or control panel.

Why is the image not displaying even though the monitor is on?

Check that the signal cable (HDMI) is properly connected to the monitor and computer. Ensure that the selected input source matches the port used (HDMI1, HDMI2, etc.). Also check that the computer is on and the resolution is compatible (3840x2160 recommended).

How to adjust the screen brightness?

Press the Menu button to open the OSD. Go to 'Video Settings' then adjust 'Brightness' (backlight) and 'Black Level' (software adjustment). Brightness effectively affects screen clarity.

How to enable HDR function?

In the OSD menu, go to 'Miscellaneous settings' > 'Other settings' and set 'HDMI 4K' to 'Enhanced'. Then in 'Video Settings', select an HDR mode (e.g. 'Bright HDR'). Ensure that the content and connected device support HDR, and enable HDR in Windows 10 if necessary.

The speaker sound is not working, what to do?

Check that the speakers are enabled in the OSD menu: 'Audio Settings' > 'Speaker' set to 'On'. Make sure the volume is not at zero and mute mode is not activated. If you use the line out, sound continues from the speakers; set volume to zero if using headphones.

Can I play video or audio files via the USB port?

Yes, the USB port allows multimedia file playback. Select 'Media' as the input source. You can view photos (jpg, png), listen to music (mp3), or watch videos (mpeg, avi). However, playback may be limited depending on format and resolution (e.g. MP4 video up to FHD).

How to clean the screen without damaging it?

Turn off the monitor and unplug all cables. Use a soft cloth specially designed for LCD panels. Never use cleaners containing alcohol or acetone. Do not spray liquid directly on the screen; apply cleaner to the cloth. Wipe gently without pressing.

What is the VESA compatibility for a wall mount?

The monitor uses a VESA standard of 200 x 200 mm. Choose a compatible wall mount. Ensure the mount can support the monitor's weight (6.5 kg without stand). Remove the monitor's stand first before installation.

Why is the power LED not lighting up?

Check that the power cord is properly plugged into both the monitor and a working electrical outlet. Try another outlet. If the problem persists, contact JAPANNEXT customer service.

How to contact Japannext customer service?

You can reach support by phone at 09 70 70 80 90 (Monday to Friday, 9am-5pm) or via the contact form on the website https://japannext.fr/pages/contact. Keep your proof of purchase handy.

• Monitor frame: Wipe with a soft cloth dampened with a mild cleaner.

The symptoms listed below are normal conditions for the monitor

• When first used, the screen may flicker due to the nature of the backlight. If this symptom appears, please turn off the monitor and then turn it on again.
• Depending on your desktop setup, displayed colors, and brightness, brightness may appear uneven.

USB device screen and operations

When you select “Media” for source selection, it is the output of the USB device connected to the USB terminal on the back of the product.

You can select or view data files.

• Media selection

Medias	Content	Comment
photo	You can watch image data	.jpg/.jpeg/.png etc.
music	You can listen to music data	.mp3 etc.
film	You can watch video data	.mpeg/.avi etc.

*The above information is for reference only, and even if mentioned, it may not be usable depending on the file format. Additionally, playback may not be possible depending on the data resolution.

Examples :

MP4 Video: Only supports up to FHD (1920 x 1080)

JPEG: Supports resolution up to 4K

JPG: only supports up to 1024 × 768

• Example of control panel (when viewing a movie)

If you press the selection button on the remote control while each data is displayed, the control panel will be displayed. Use ◀▶ buttons to move and press OK button to confirm.

HDR stands for High Dynamic Range. This is a display technology that can express a wider range of brightness than the conventional SDR standard dynamic range.

Set HDR in the screen menu (OSD) to automatic.

The monitor can then automatically enable HDR functionality if the player and content are compatible.

Depending on Windows 10 settings, HDR may not display correctly.

Check if HDR settings in Windows 10 are enabled or disabled.

How to open the settings screen:

Settings > System > Display

Depending on your graphics card specifications, photos and text may not display correctly when the monitor's HDR function is enabled.

Note : If you enable HDR, some OSD menu functions will not be available.

Note : To enable HDR, the connected device and content must support HDR.

Description: Windows 10 Fall Creators Update (version 1709), if the graphics card does not support HDR, Windows HDR settings will not be displayed.

The HDR function is enabled only for HDR content.

If you enable HDR settings in Windows 10, your desktop screen may appear darker than if you set it to Standard Dynamic Range (SDR) mode. This is not a malfunction, but rather the result of the monitor interpreting HDR and SDR signals differently.
